Yarn E extends through lig. 13 is a view similar to Fig. 14 but showthe eye 9 carried by an actuating bar lll, which insr the parts of thev mechanism advanced one functions in a similar manner to bar 8, namely, as step or movement toward forming the stitch; upwardly and downwardly, and also moves longi- 55 tudinally during the functioning of the mechanism. Also a suitable control may be used for actuating these bars, as, for instance, an ordinary pattern chain. It will be understood that the particular construction of the knitting machine and pattern chain, if used, forms no part of the present invention but these members are shown to illustrate how the stitch or knitting action is produced. Associated with each pair l of yarns 5 and 6, is a needle H for alternately engaging the respective yarns for forming the respective loops I2, as shown in Figs. 9 and 10. It will be understood that there is one needle H for each pair of warp yarns and 6, and if there are forty pairs of warp yarns there should be forty needles in use.

When the device is functioning, the needle, for instance needle Il, interlocks with yarn 5 and pulls the same to form a loop I2 and then moves back to the position shown in Fig. 9 and interlockswith yarn 6 which is immediately pulled to form a second loop i2. lt will be seen, therefore, that the respective yarns of each pair will be alternately formed into loops. Immediately after each loop has been formed the ller feed i3 will move across the respective needles, as shown in Fig. 1, so that the filling yarn i4 will be laid on top of the formed loop. As illustrated in Fig. l, the ller feed i3 has just moved from the dotted position shown in Fig. 1 to the full-line position. As soon as the respective needles il function the filler feed will nove back to the dotted position shown in Fig. 1 where it will remain stationary until the needles again function. A single strand of yarn is thus fed back and forth across the loom after each functioning of all the needles I I.

As shown in Figs. 6 to 8, inclusive, when the eye 1 is in its neutral or starting position the yarn 5 thereof Will be at the right side of the needle Il. The numeral H is used merely to identify a particular needle in describing the operation. When the parts are in the position shown in Fig. 6, the bar 8 is moved longitudinally and, consequently, the yarn 5 is moved to a diagonal position as shown in Fig. 7, and then downwardly as shown in Fig. 6, while the needle il' remains stationary. As soon as this occurs, needle Il will begin to function and move from 5G the outer position shown in Fig. 9 Ato the inner position shown in Fig. 10. This is illustrated in diagram in Fig. 8 and will result in the needle interlocking with yarn 5 and forming a loop. As soon as the loop has been formed the needle re- 55 turns to the position shown in Fig. 9 and the eye 1 returns to the position shown in Fig. 6, where it will remain stationary until bar l0 moves longitudinally and then swings downwardly so that the needle Il may repeat the C0 operation in respectv to yarn 6. This is illustrated in Figs. 12 to 17 inclusive. As shown in these figures, the eye 9, for instance, holds the yarn 6 at the left of the needle Il. The eye 9 moves to the right as shown in Fig. 13 and then c5 downwardly as shown in Fig. 14, after which the needle is quickly moved to the position shown in Fig. 10 to produce a loop. This action is shown particularly in Figs. 15 to 17 in diagram.

Each time a row of loops is made the filling yarn feed i 3 moves from one extreme position to the other, as illustrated in Fig. 1. The result will be the production of the fabric shown in Figs. 2 to 5, inclusive.

In the fabric shown ordinary textile yarn, cotton, silk, or other suitable material, is used for the respective pairs of warp yarns 5 and 6, while the filling yarn is shown as made of ribbons of Cellophane. When the loops are tightened around the filling yarn, they will crumple or coil somewhat, as illustrated in Fig. 5. It will be evident that other forms of filling yarn may be used and of other material without departing from the spirit of the invention.

As illustrated in Fig. 4, the respective yarns 5 and 5 are provided on the rear face with base sections or floats i5 and i6. On the front face there are provided interlocking loops l2 and I2". From Fig. 5 it will be seen that the float t5 of yarn 5 extends through the loop I2 of yarn 6 and the float I6 extends through the loop I2' of yarn 5. Float i 5 and float I6 extend through alternate yarns i4, whereby the warp yarns not only hold or tie in the filling yarn but interlock with each other in such a way that the warp yarns will not ravel.

If desired, when the filling yarn has been exhausted, the machine could continue to function and the respective needles H and associated parts would function to form the various interlocking loops, as shown in Figs. 2 to 5 inclusive, whereby the pairs of Warp yarns would form interlocked extensions projecting beyond the body of the fabric.

I claim:

A fabric comprising lling yarns extending the full width of the fabric and pairs of warp yarns for tying said filling yarns together, each pair of said warp yarns having base sections arranged parallel to each other and side by side, each of said base sections extending across two of said filling yarns, said base sections of one warp yarn of a given pair being staggered in respect to the base sections of the other Warp yarn of said given pair so as to tie the filling yarns together, each base section at the space between each pair of filling yarns extending substantially at right angles to the length of the fabric from the reverse surface of the fabric to the obverse surface and on the observe surface merging into hook-shaped members, the loop of one hookshaped member interlocking with the shank of the next adjacent hook-shaped member on the obverse surface of 4the fabric opposite the space between the filling yarns whereby the hookshaped member of one warp yarn will extend across one filling yarn and the hook-shaped member of the next adjacent warp yarn will extend across the next filling yarn in longitudinal alignment with the first hook-shaped member and so on for the full length of the fabric.
